[Q] Anyone has hot issue while charging?

My Note 2 feels pretty warm while charging, even when I turned it off, it was still warm.
Anyone has similar issue?

It's perfectly normal to get warm while charging.

Filling up 3100 mAh takes power man.

The hot part is near the camera not the battery and even when i turned it off, is it ok?

Odd. Mine doesn't get hot while charging. And I live in a tropical country at that.

It's 2Ah battery charger, twice as powerful as normal phones 1Ah charger. Gottabe careful with it.

LG WCP-700 Wireless Charger Won't Stop Charging

I've dug through the other wireless charging threads and even tried posting my issue within a couple but cannot seem to get a response. So here we go:
I have owned the WCP-700 Wireless Charger since January. It worked flawlessly with my Nexus 4 and has been working flawlessly with my Nexus 7 (2013) as well. By "flawlessly" I mean that it charges the Nexus 4/Nexus 7 until full. Once the Nexus 4/Nexus 7 is full the blinking green light at the top turns a solid green and it stops charging the device until the battery falls below 95%, then it starts charging it again (AKA the "Trickle Charge").
However, with my Nexus 5 I am noticing that while the WCP-700 charges the phone just fine, it doesn't stop charging when the device is full. When the Nexus 5 indicates that it is 100% full, the wireless charger continues trying to charge and the green light remains blinking. If I leave the phone on the charger overnight I wake up to find the phone rather hot, which concerns me.
Does anyone else have experience with this charger or the WCP-300 that can confirm whether or not your charger stops charging the phone when full, as it should? Does your green light turn solid when full?
I hate the idea of having to get a new wireless charger when this one worked so well with the other Nexus devices, but for the time being I've resorted back to plugging the Nexus 5 in with the stock charger to prevent from overcharging it.

I have the same charger and my phone doesn't get hot. The light doesn't turn solid green either but I think it stops charging

Overcharging isn't really an issue as there is a chip that shunts the power when the battery gets full. Plugging into your USB charger would still overcharge it if overcharging were a problem.
People everywhere and concerned about the lights on their qi chargers not responding to a full battery and thus become concerned with overcharging. Right now it looks like the N5 doesn't communicate back to the charger when full, honestly it's probably less the phone and more something in KitKat. Regardless, the charging circuits in most new phones are designed to prevent overcharging.

I have the same charger and I personally love that the N5 exhibits this behavior! My biggest gripe about the n4 is that the phone stops charging before 100% and then remains awake and drains down to 95% or lower before charging again. With this phone it always is "charged." Same with the Nexus 4 Orb. Charges continuously like a cable charge would... and it's about time!
Fun fact... you can get your n7 (2013) to charge fully on wireless by shutting the device off while it's on the charger. The device will not stop charging and you end up with a truly full charged device when you take it off the charger.

It is impossible to overcharge the Nexus 5. Wired or wireless.

Thanks for the replies guys. What you are saying makes sense. Concerns alleviated. :highfive:

I disagree. I own a power outlet with build-in Watt meter.
When I charge Nexus 4 you can read continuously 4-7W power consumption. When the phone is charged this number drops to 0 and the led turns green.
When I charge Nexus 5 you get average 6-8W power consumption, but at the end, when the battery is full at 100% you still get around 3W power consumption, even hours after the battery is charged. All this overcharging is easily detected when you remove the device from the charging pad and you'll notice the produced heat on the back of the Nexus 5.
Unfortunately I experience the same issue with Nexus 7 (bought in EU), so basically I have only Nexus 4 properly working on two different wireless chargers.

Will it eat through my battery cycles though? (will it shorten the battery's life span?)

[Q] Very slow charging

This device charges slower than any device I've ever used. I put it on the charger at around during 2 am woke up this morning around 10 and it only charged around 50% what's up with that? Is something wrong with my device or is this normal?

Are you using the stock plug and cable?
It should take max 8hrs but really around about 5/6 hours to charge from 5% to 100%.

Definitely check your charger or connection.

[Q] LG G4 Charging Very Slowly

Hi, I just got an LG G4 yesterday. Charging using stock charger, or any other charger I had no problems with S3 before, is really slow. As in obviously slow. The unit is estimating 3-4 hours to charge 30%-40% of battery. Once it took around 20-30 minutes to just charge 5% of battery.
Using Ampere app it is showing on average just 270mah charge. Sometimes it registers 1660mah, then it drops down significantly and settles with 270mah.
Using the dual sim model if that's any help.
Is this a new battery thing? Should I insist to have the unit (or the battery) replaced? Is this a hardware or a software issue? Even if i insist to have this replaced I want to be able to explain that this is a factory defect.

Same problem here..
Really annoying.

Same here, I think it charges at full speed when the screen is off...
I got myself a QC2.0 charger and its doing exactly the same.
It does appear to charge faster with it while the screen is off but I'm wondering if there is an update to the device that needs to be done to fully support QC2.0

i've buy an Aukey Turbo Charger Adapter.
Then my G4 has fast charging more about 75%

I've seen the same thing happen on mine. Highest current I've seen was 1650 mah. And that's with the screen off. Leaving the screen on it reduces to 270 mah

I had the same problem but it stopped after about week. Now it charges quite quickly and that's not with the fastcharge that isn't too impressive.

Same issue. Charging went from 2% to 46% in about 3.5 hours and it says it's still another 4 hours before it completes charging. Totally annoying.

i using the Aukey Turbo Charger and get around 1%-1.5% every min i have done 30%-70% in like 40min

I have a HTC quick charger that I used with my M8. It works well with the G4. With the screen off I have had nearly 2 A charging. It is much less when the screen is on.

Just got my G4 and it's doing the same thing.

are you using the screen while its charging tho? how many times have you charged it already since you got it?

my post was made during 2nd ever charging. i did turn on screen occasionally, but not like it was on all the time.
last night charge was shorter - around 5.5 hours.

This is really annoying trying to stream music and navigation sometimes losses a charge. With nexus 5 I usually gained 30 plus percent on my way to work on 40 ish minutes with car charger.

It "might" be a software limitation, to avoid pushing the battery too hard in its early cycles. Same as a brand new car, they usually tell you not to drive too fast for the motor to actually run with optimal parameters.
[2cents]

I am also experiencing the same. I am getting 640mA. It is really frustrating. Yesterday I connected the phone with the provided cable with G4 with my laptop. And i was using the phone, not heavy using. And actually the battery was draining, rather than charging. I got so frustrated. I found the phone actually charges better while staying idle & screen off, but not very promising.

Yep, add me to that list too. T-Mobile G4 with screen off and no use because I'm driving almost all day just to see a 5-10% more charge after driving almost 2 hours. The original charger behaves the same way too. The only fix I've found is to turn the phone off and charge it. It charges really fast that way only.

Charged mine from 2 to 100% in under 2 hours with my note 4 charger

@fatboypup does this also work with screen on? Imagine using gmaps in the car, screen and gps active - it would be a pity if the g4 lost power in such a situation when on the car charger

As I noted above it is an issue with cars too. I'm lucky to gain 5 to 10 percent with navigation and streaming music in 45 mins. The same situation with nexus was over 30%.

Does this behavior stay or is it only for the first charges? Is there anyone who has no slow charging with screen on? Is the g4 gaining at least some percent when navigating with gmaps?

slow fast charging

It takes my 2xl 2.5 hours to fully charge..in comparison my v20 takes an hour 45 minutes and Moto x play an hour 30 minutes.. the device does not get warm while fast charging while the other 2 does.. fast charging on this phone is a joke

The battery needs to be warm, at least 24°C... It's a known issue, the power delivery feature doesn't start if the battery is cold... I warm the battery everytime before charging the phone and you can notice the difference.

Is this for real?
Care to give us the source for this as I havent found it nowhere in my Pixel 2 XL manual.
And now everytime I plugged in my phone (sometime) it just wont charge immediately and sometime it doesnt even start charging at all (I left it plugged in at night, and battery still not charged at all in the next morning)
So now, everytime I plug, I would have to always carefully check the charging "icon", whether it is "charging" immediately or if not I will have to unplug and replug it till the charging "icon" is ON and sothat I will have a full charged phone in the next morning (bit annoying actually). Sometime I even have to change a charging adapter or cable (and yes, I always use OG pixel 2 xl charger, but when it fails or not charging immediately I will havr no choice but use my samsung charger). And Now I will have better luck with slow charginv adapter i.e. 1 Amp charger, but yes it will take 5-6hrs instead of the 2.5hrs charging time that I used to have.
But what makes me questions myself is that, if all those "temp" thing is true, but why for the last couple of months I had this phone, it is immediately charging fine as its being plugged. Why now with the new behavior?
Thanks in advance

There's a very lengthy thread about the charging speed:
https://forum.xda-developers.com/pixel-2-xl/review/charging-speed-t3685546/page39
It actually used to take nearly 3 hours when the phone first came out. Now it takes me 2 hours and 10-15 minutes to go from 1%-100%. It's definitely not the fastest to hit 100% but it gets to 85%, give or take, just as fast as most phones. Especially when comparing amount of mAh.

It's my opinion that Google is gun shy after the battery failures on the 6P.
